Pokémon Origins tells the story of the very first Pokémon video games, Pokémon Red Version and Pokémon Blue Version, including the first steps of our hero Red as he sets off from Professor Oak's laboratory. As he explores the Kanto region, he'll encounter Team Rocket, battle his rival, and challenge the Pokémon League. Pokémon Red and Pokémon Blue launched in North America in September 1998.

In the anime's story, Red encounters a strange Pokémon in the fierce battle with Team Rocket's leader Sakaki (Giovanni). Rival Green, Professor Ōkido (Professor Oak), Gym Leader Takeshi (Brock), Gym Leader Takeshi (Brock), Red's mother, and Team Rocket also appear in this special set in Kanto, the first region ever seen in the Pokémon franchise.

@takashichea: Looks like the quote didn't show up on my post. How messed up. XD Also, you repeated Takeshi's (Brock's) name twice.
